RIUSKA

This is part of an integrated simulation system for building services design and facilities management. It can be used in everyday design processes and covers the thermal simulation needs of the whole-building life cycle.
The user can add building envelope materials, internal loads, and HVAC into the created 3D model and perform thermal calculations. RIUSKA can be used for space simulations to dimension cooling or heating equipment, or for energy calculations of the whole building. As a calculation engine RIUSKA is presently using DOE-2.1E.

The IFC file format is used to import the building 3D model into RIUSKA. The 3D model must be created in some IFC-compliant 3D modeling tool. RIUSKA currently supports IFC 2x3 (CoordinationView with SpaceBoundaryAddOnView).
